For example, applications may include aweb browser, a camera application, a dictionary application, atranslator application, a data transmission application, a music playerapplication, a movie player application, a phone application, a messageapplication, a social communicator application, a map application, apicture folder application, a broadcasting application, a gameapplication, a fitness application, a payment application, a memoapplication, a calendar application, and a phone book application, butare not limited thereto.

“Middleware” may include a plurality of modules that are prepared inadvance to provide functions that are commonly demanded by variousapplications. Middleware may provide functions via application programinterfaces (APIs), such that applications may efficiently utilizeresources in a device. For example, middleware may include at least oneof a plurality of modules including an application manager, a windowmanager, a multimedia manager, a resource manager, a power manager, adatabase manager, a package manager, a connection manager, anotification manager, a location manager, a graphic manager, and asecurity manager. Furthermore, if a device has a phone call function,middleware may further include a phone call manager to manage a voicecall function or a video call function. Middleware may further includeruntime libraries or other library modules.

According to an exemplary embodiment, the first device 100 may receive acall request, e.g., an incoming call from the second device 200. Inother words, a second user USER2 of the second device 200 may attempt toestablish a phone call to a first user USER1 of the first device 100.Therefore, the first user USER1 may be referred to as a receiver,whereas the second user USER2 may be referred to as a caller or asender.

A phone number of the second device 200 may be displayed on a displayscreen of the first device 100 (phone number 12, FIG. 1A), and the phonenumber 12 of the second device 200 may be referred to as a caller ID ora caller's number. If the phone number 12 of the second device 200 isincluded in contact information, e.g., a phone book stored in the firstdevice 100, a name 11 of the second user USER2 stored in the contactinformation may be displayed on the display screen of the first device100.

A phone number 14 of the first device 100 may be displayed on a displayscreen of the second device 200, and the phone number 14 of the firstdevice 100 may be referred to as a receiver's number. Furthermore, ifthe phone number 14 of the first device 100 is included in contactinformation, e.g., a phone book stored in the second device 200, a name13 of the first user USER1 stored in the contact information may bedisplayed on the display screen of the second device 200.

According to an exemplary embodiment, the first user USER1 of the firstdevice 100 might not be able to respond to an incoming call from thesecond device 200. For example, the first user USER1 may be in asituation in which it is difficult to respond to the incoming call orthe first user USER1 may not want to respond to the incoming call fromthe second user USER2.

According to an exemplary embodiment, when an incoming call is receivedfrom the second device 200, the first device 100 may automaticallygenerate a response message (RM) by referring to information regardingan application that is being currently executed or previously executedand may automatically transmit the generated response message RM to thesecond device 200. To notify the first user USER1 that the responsemessage RM is transmitted, the first device 100 may provide anotification that transmission of the response message RM is completedon the display screen of the first device 100 in the form of a message,for example. Here, the response message RM may include informationregarding a current situation, a future situation, or both a currentsituation and a future situation of the first user USER1, or may be asimple response message.

According to another exemplary embodiment, when an incoming call isreceived from the second device 200, the first device 100 may provide auser interface (UI) element corresponding to the incoming call on thedisplay screen of the first device 100. Here, the UI element may displayoptions with respect to the received incoming call including allow,reject, or transmit a response message. If the first user USER1 selectsto reject the incoming call or to transmit a response message, the firstdevice 100 may automatically generate a response message RM by referringto information regarding an application that is being currently executedor previously executed and may automatically transmit the generatedresponse message RM to the second device 200. Here, the response messageRM may include information regarding a current situation, a futuresituation, or both a current situation and a future situation of thefirst user USER1, or may be a simple response message.

According to another exemplary embodiment, when an incoming call isreceived from the second device 200, the first device 100 may provide auser interface (UI) element corresponding to the incoming call on thedisplay screen of the first device 100. Here, the UI element may displayoptions with respect to the received incoming call including allow,reject, or transmit a response message. If the first user USER1 selectsto reject the incoming call or to transmit a response message, the firstdevice 100 may automatically generate response message candidates byreferring to information regarding an application that is beingcurrently executed or previously executed and provide the generatedresponse message candidates on the display screen of the first device100 together with general frequently used messages. As described above,the first device 100 may provide a response message list includingresponse message candidates and general frequently used messages, theresponse message candidates may include information regarding a currentsituation, a future situation, or both a current situation and a futuresituation of the first user USER1, and the general frequently usedmessages may be simple response messages. Next, when the first userUSER1 selects one response message in the response message list, thefirst device 100 may transmit a selected response message RM to thesecond device 200.

Here, the “current situation” may refer to a reason that the first userUSER1 is unable to respond to an incoming call at a time point ofreception of the incoming call, the reason determined by referring toinformation regarding an application that is being currently executed orpreviously executed and may be a specific activity, a location, or aroute of the first user USER1. For example, if a navigation applicationis being executed on the first device 100, a current situation of thefirst user USER1 may be determined as ‘driving’ by referring toinformation regarding the navigation application (e.g., if thenavigation application determines the phone is moving at or above apredetermined speed). For another example, if a fitness application isbeing executed on the first device 100, a current situation of the firstuser USER1 may be determined as ‘exercising’ by referring to informationregarding the fitness application. As another example, if a phoneapplication is being executed on the first device 100, a currentsituation of the first user USER1 may be determined as ‘on the phone’ byreferring to information regarding the phone application.

The “future situation” may be a change of situation of the first userUSER1 after termination of an incoming call, which may be estimated byreferring to information regarding an application that is beingcurrently executed or was previously executed and may correspond to anestimated point of time when the first user USER1 will be available torespond to an incoming call. For example, if a navigation application isbeing executed on the first device 100, a future situation of the firstuser USER1 may be estimated to ‘arrive at a destination in a fewminutes’ based on information regarding the navigation application(e.g., a destination set by the first user USER1, current trafficconditions, etc.). As another example, if a fitness application is beingexecuted on the first device 100, a future situation of the first userUSER1 may be estimated to ‘finish exercise in a few minutes’ based oninformation regarding the fitness application (e.g., a target exercisetime set by the first user USER1). As another example, if a phoneapplication is being executed on the first device 100, a futuresituation of the first user USER1 may be estimated to ‘finish a phonecall in a few minutes’ based on information regarding the phoneapplication (e.g., an average call time of the first user USER1).

According to an exemplary embodiment, an application that is beingcurrently executed or previously executed on the first device 100 may beexecuted by the first user USER1. In other words, functions of anapplication that is being currently executed or was previously executedon the first device 100 may be initiated based on a user input, such asa touch input from the first user USER1. The first user USER1 mayintentionally execute an application installed on the first device 100to perform a particular task. For example, the particular task may bedriving, exercising, making or receiving phone calls, sending orreceiving messages, inputting schedules, reserving movie tickets,reserving transportation tickets, watching movies, playing games,internet banking, etc. As described above, an application that is beingcurrently executed or previously executed on the first device 100 arenot limited to applications that are executed to determine a currentsituation of the first user USER1 or to estimate a future situation ofthe first user USER1 and may also be applications intentionally selectedby the first user USER1 to perform particular tasks.

The first device 100 may generate a response message RM by using anapplication or middleware. Detailed descriptions thereof will be givenbelow.

According to an exemplary embodiment, the first device 100 may generatea response message RM by using a phone application or a messageapplication. In detail, a phone application or a message applicationinstalled on the first device 100 may receive information regardinganother application via an API and generate a response message RM. Here,the response message RM generated by the phone application or themessage application may be transmitted to the second device 200 via themessage application.

According to another exemplary embodiment, the first device 100 maygenerate a response message RM by using a separate dedicatedapplication. In detail, a separate dedicated application installed onthe first device 100 may receive information regarding anotherapplication via an API and generate a response message RM. Here, theresponse message RM generated by the separate dedicated application maybe transmitted to the second device 200 via a message application.

According to another exemplary embodiment, the first device 100 maygenerate a response message RM by using middleware. In detail, aparticular module of middleware of the first device 100 may collect andmanage information regarding various applications. Furthermore, aparticular module of the middleware may generate a response message RMby using information regarding an application. Here, the responsemessage RM generated by the particular module of the middleware may betransmitted to the second device 200 via a message application.

For example, methods of generating response messages RM via a phoneapplication or a message application, a separate dedicated application,or middleware in a case in which a navigation application is beingexecuted on the first device 100 at a point of time when an incomingcall is received from the second device 200 will be described below indetail.

According to an exemplary embodiment, a phone application or a messageapplication installed on the first device 100 may receive informationregarding a navigation application via an API and generate a responsemessage RM. In detail, the phone application or the message applicationdetermines a current situation of the first user USER1 as ‘driving’based on information regarding execution of the navigation applicationand may estimate a future situation of the first user USER1 to ‘arriveat a destination in 30 minutes’ by referring to information regardingthe destination and information regarding current traffic conditionsfrom the navigation application. Therefore, the phone application or themessage application may generate a response message RM saying “I amdriving right now. I will contact you in 30 minutes.” The first device100 may transmit the generated response message RM to the first device100 via the message application.

According to another exemplary embodiment, a separate dedicatedapplication installed on the first device 100 may receive informationregarding a navigation application via an API and generate a responsemessage RM. In detail, the separate dedicated application determines acurrent situation of the first user USER1 as ‘driving’ based oninformation regarding execution of the navigation application and mayestimate a future situation of the first user USER1 to ‘arrive at adestination in 30 minutes’ by referring to information regarding thedestination and information regarding current traffic conditions fromthe navigation application. Therefore, the separate dedicatedapplication may generate a response message RM saying “I am drivingright now. I will contact you in 30 minutes.” The first device 100 maytransmit the generated response message RM to the first device 100 via amessage application.

According to another exemplary embodiment, a particular module ofmiddleware or an OS of the first device 100 may receive informationregarding a navigation application via an API and generate a responsemessage RM. In detail, the particular module of the middlewaredetermines a current situation of the first user USER1 as ‘driving’based on information regarding execution of the navigation applicationand may estimate a future situation of the first user USER1 to ‘arriveat a destination in 30 minutes’ by referring to information regardingthe destination and information regarding current traffic conditionsfrom the navigation application. Therefore, the particular module of themiddleware may generate a response message RM saying “I am driving rightnow. I will contact you in 30 minutes.” The first device 100 maytransmit the generated response message RM to the first device 100 via amessage application.
